Title: Recording apparatus
IPC: G06K1/12
Filed: 1971-07-08
Abstract: 1356990 Magnetic recording HONEYWELL INFORMATION SYSTEMS Inc 8 July 1971 [31 Aug 1970] 32217/71 Heading G5R Information recorded in a card, for example a credit card, in binary form by the presence or absence of embedded pieces of soft magnetic material, i.e. material having a high permeability and a low remanence, is transferred to a magnetic recording tape mounted in a cassette by moving the cassette across the card and simultaneously winding the tape from the supply reel to the take-up reel, so that in effect the tape is laid across the card, and arranging that a magnet is moved with the cassette above the tape so that as the tape is transported within the cassette it is magnetized by the magnet, either uniformly or in a distorted fashion when an embedded piece of soft magnetic material is passed over. The card also contains outwardly embossed data which is printed at the same time as the magnetic data is transferred. A card 2, Fig. 1, and appropriate pieces of paper are positioned so that they can be traversed by a carriage, Fig. 3, mounted on rails 5, 6 extending across a baseplate 1. The carriage includes a tape cassette containing two reels 23 of tape mounted on spindles 32, 35. Projecting into the cassette immediately above the tape is a narrow magnet 30. In operation the carriage is moved manually along its rails 5, 6 and as it moves a chord (58, Fig. 4, not shown) rotates a spring loaded drum 57 to rotate the tape take-up reel 31 via a oneway clutch arrangement 64, 65. This causes the data in the card to be transferred to the magnetic tape in the manner mentioned above. At the end of the manual traverse, the spring loaded drum 57 rewinds the chord and returns the carriage to its rest position, rewinding of the tape being prevented by the one-way clutch. The carriage also incorporates a roller (20, Fig. 2, not shown) which causes the outwardly embossed data on the card to be printed. It is also possible to cause manually set data to be recorded and printed, this being effected by setting levers 90, Fig. 1, each of which moves a pair of wheels 80, 86 and an indicator 96, the wheels 80, 86 being positioned respectively under the path of the recording tape and the print roller.

Title: Improvements relating to automatic defrost control mechanism for refrigerators
IPC: F25D21/00
Filed: 1952-12-19
Abstract: 742.995. Thermal switches. GENERAL ELECTRIC CO. Dec. 19, 1952 [Dec. 19, 1951], No. 32251/52. Class 38(5) [Also in Group XXIX] A refrigerator control having a cycling refrigerating action and automatic defrosting action comprises a pivoted arm 8 for operating a switch or valve 4 for starting or stopping refrigeration and actuated by a thermal element 20 against a spring 22, a pivoted interfering member, e.g. the toggle 36, 37, movable between a position where it acts as a stop for the arm to a position where it frees the arm. means biasing the toggle against a cam 28 which allows the toggle to move between its two positions, and means actuated at a pre-determined abnormally high maximum temperature when the toggle is in its stop position for shifting the toggle in the opposite direction to free the arm. 'The arm has a first part 9 pivoted at 14 and connected by a toggle spring 11 to a second part 10 flexibly supported at 9 by the bracket 16 and carrying a magnetic yoke 7 whereby a magnet 6 carrying the valve moves with snao action. Each time the arm moves upwards under the cycling action of the valve and thermal bellows 20 responsive to evaporator temperature, a pawl 29 on the part 9 engages a gear wheel 31, and progressively rotates the cam 28. A tongue 41 on the toggle rides on the cam which thus keeps a stop 39 out of the path of a member 40 on the part 10. When a cam slot 51 comes opposite the tongue a spring 48 pulls the toggle over its dead centre so that the stop 39 prevents downward movement of the part 10 due to a temperature rise, and thus prevents the opening of the valve and the start of the refrigeration cycle. The temperature thus increases and since the part 9 is held against a stop 58, continued expansion of the bellows pivots an arm 26 about a knifeedge 53 against a spring 55 until the arm 26 contacts an arm 52 of the toggle and snaps the stop out of the way of the part 40, so that after defrosting the normal refrigeration cycle re-commences. The spring-adjusting screw 57 determines the defrosting temperature independently of the spring-adjusting screw 24 determining the refrigerator temperature setting. The toggle may be replaced by a lever or a lever carrying a roller stop. Specification 695,850 is referred to.

Title: Improved hydroforming catalyst
IPC: B01J23/28
Filed: 1955-11-15
Abstract: An hydroforming catalyst supported on a zinc aluminate (spinel) base is stabilized against the adverse effect of water by adding up to 10 per cent by weight of zirconia.  Hydroforming catalysts specified are, cobalt molybdate, or oxides of Mo, Cr, W and V. The support may be prepared by adding a solution of zinc sulphate or nitrate to sodium aluminate in equimolecular proportions, or by hydrolysing aluminium alcoholate with a heat-decomposable zinc salt, e.g. zinc acetate.  A solution of zirconyl nitrate, sulphate or acetate is mixed with the spinel base which may be in the form of a hydrogel, dry powder or micro spheres, and after standing, the mixture is dried and calcined at 650 DEG  to 1400 DEG  F. for 6 to 16 hours, and is then finally impregnated with ammonium molybdate and dried to yield a product containing 10 per cent MoO<ta>3<te>.  Alternatively, the ammonium molybdate may be added simultaneously with the zirconyl salt solution.  The product may be formed into cylindrical pellets. Examples are given of treating naphtha under hydroforming conditions with the catalyst in both wet and dry state.  The catalyst may be regenerated by burning off deposits at 1000 DEG  to 1200 DEG  F. at the pressure used in the hydroforming reaction or at a lower pressure, alone or in the presence of hydrogen or other reducing gas.
